Does anyone know of a way to semantically tag parts of photos with the contents of said photos? Particularly people depicted in a group photo?

For example:


I'm thinking something along the lines of an image map, where the co-ordinates define the area where a specific person is depicted?

I've been scouring this site because I thought that there was a question very close to this one in the past, but alas about the closest I can find is about tagging in general ("Tagging in Semantic Web"). I would think that whatever you find, you would want the representation of people in a group photo to be their FOAF profile, if available. You could do this simply with rdfs:seeAlso barring the use of some better property.

EDIT: see comments. @Signified found the question I was looking for: "Ontology to annotate an image and parts of it" . Of the suggestions in this question I like in particular the ontology that @zazi found "A Lightweight Ontology for Describing Images" and would suggest you take a look.

Also, this might be related: http://di2.deri.ie/index.php?id=612&tx_ttnews%5Btt_news%5D=246&cHash=114b19f118 ...though I don't know if a vocabulary/ontology is available online.

Eric, there is draft for a "Media Fragments URI 1.0" at W3C. It is still a draft, but should address what you describe (the document's main focus is video, but the "spatial dimension" should also apply on an image. I hope this helps.

I just found this AKTive Media and its relevant SourceForge page, which can be used for image annotation. Here is the description:

AKtive Media is an ontology based cross-media annotation (Images and Text) system. Our goal is to automate the process of annoation by suggesting knowledge to the user in an interactive way while the user is annotating and hence minimizing user effort.

I don't know what ontology that is used on it. Also, it's a bit outdated (Last update: 2010-01-18).

The W3C Group Report Image Annotation on the Semantic Web may be of interest for your purpose.

Fellahst, actually, the media fragment URI 1.0 document supersedes this report I believe. The relevant Working Group grew "out" of that Incubator Group...

Thanks Ivan for the update on this spec.
